It was a Sunday night in December in New York, and Harvey Weinstein was wearing a suit. What could possibly have compelled him to do that?

The Cinema Society screening of Madonna's new movie, W.E., at MoMA, and wise words from his wife.

"I was wearing a Giants T-shirt, and the English voice told me this would be a fashion crowd, so she laid out this suit," joked Weinstein, referring to his wife, Marchesa designer Georgina Chapman, as he introduced Madonna's latest directorial project.

The film examines the legendary love between American divorcee Wallis Simpson (Andrea Riseborough) and the king who gave up the British throne to marry her, subsequently living out their lives in exile as the Duke and Duchess of Windsor. Woven into the story is the modern day tale of Wally (Abbie Cornish), an unhappily married young woman obsessed with the Duchess and her story.

"It was a story that always intrigued me, a story about true love and sacrifice," said Madonna, looking stupendous in a black leather jacket, black sequined top and black pants, all by Roberto Cavalli, complete with Van Cleef & Arpels white gold and diamond earrings.

The Duchess has great style; if Madonna could have owned any of her accessories, which would it have been?

"The cross bracelet," she told FashionEtc without hesitation. The bracelet is prominently featured in the film; each inscribed cross was made of precious stones, and each represented a significant event in the couple's courtship.

Her glorious cache is brilliantly displayed at Christie's through December 12, after which it will be sold and scattered around the world, with each piece's provenance forever guaranteed. The low estimate for the entire collection is $30 million, but it is widely expected to fetch a lot more. After all, who wouldn't want a little piece of Liz?

"She was the great jeweler collector of our time, both in terms of historic stones, and of contemporary jewelry makers," Marc Porter, Chairman of Christie's America, told me as we toured the exhibit. "Van Cleef & Arpels, Bulgari, Cartier, JAR—all the great makers are represented by the very best of their work."

"The fashion is a total explosion of color and quality," Porter continued. "It's built on a foundation of Christian Dior, for 40 or 50 years from the house, when Dior was there, all the way until the end when Galliano was designing. If you look at the fashions through the second half of the century, as soon as she left the studio system, she started buying her own clothing: Pucci, Dior, Valentino, Balenciaga, Tom Ford for Yves Saint Laurent, an incredible group by Michael Vollbracht, who designed the most extraordinary things you could imagine for the time when she was living in New York. It was when Warhol was here, and they were going to Studio 54. Then she started buying Chanel suits. From there she moved on to Scaasi, Adolfo, more Valentino, and finally an explosion of Versace ready to wear and couture."

Young Adult, the new movie written by Diablo Cody, stars Charlize Theron as a 36-year-old teenage book writer who is as emotionally stunted as the characters she writes about.

Having moved from her small town to the "big city," Minneapolis, she yearns to rekindle her romance with her now married-with-a-baby high school sweetheart.

She goes back home to see him, and in the process, makes an unlikely friend out of an unpopular classmate who was beaten and disabled (Patton Oswalt). The Cinema Society screening, sponsored by Dior Beauty, was star-studded.

Much of the action in the movie happens in the local bar. So was it fun to act drunk?

"The bar was genuinely fun to hang out in," said Oswalt. "The whole set was really lively and very interesting."

What was it like to work with Charlize? we asked.

"I got to work with a great actor," the charismatic Oswalt told FashionEtc. "I think she's going to have one of those amazingly insane careers—she's going to become one of those one-word people—you know, 'Charlize said to me one time'... She made everyone better. The most difficult scene to do was the love scene because I was half naked next to the hottest woman on the planet. No way I could do this next to Michael Moore or something?"

Twilight screenings are shrouded (if you'll pardon the term) in secrecy. The venue is kept under wraps until the last minute, mobile devices are checked at the door, and the vibe is unique—very insider.

"The birthing scene was kind of funny because we were a little uncomfortable and out of our element," the actress admitted. "We would be really intense—and then they would yell, 'Cut!' and it was like we were part of ER, yelling 'scalpel!', and other things. It was actually a very funny day on set."

Lisa Howard, who plays Siobhan, a vampire in the Irish Coven, had a great time bowling (yes, they went bowling) and joking around with other members of the cast.

"We all did one of those dance flash mob things to surprise the director, Bill Condon. We did the dance of the Volturi, and the dance of all of the other vampires. We all surprised him, and that was really fun!," Howard recalled.
